This book was released on 1997 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: CETTE ETUDE A POUR OBJET LA SIMULATION NUMERIQUE D'ECOULEMENTS INSTATIONNAIRES INTERNES ET EXTERNES DE FLUIDES VISQUEUX INCOMPRESSIBLES, PAR UNE METHODE DE DECOMPOSITION DE DOMAINE SANS RECOUVREMENT ET NON CONFORME (ELEMENTS JOINT) EN D.N.S. (SIMULATION NUMERIQUE DIRECTE) OU L.E.S. (SIMULATION DES GRANDES ECHELLES). LES EQUATIONS RESOLUES SONT CELLES DE NAVIER-STOKES ECRITES EN VARIABLES PRIMITIVES (VITESSE - PRESSION), ET UNE METHODE DE PROJECTION CONDUISANT A UNE EQUATION DE POISSON EN PRESSION EST UTILISEE. LE DECOUPAGE DE L'ESPACE D'ETUDE EN SOUS DOMAINES NON RECOUVRANTS CONDUIT A DES MAILLAGES LOCALEMENT STRUCTURES ET NON CONFORMES AU VOISINAGE DES INTERFACES. SUR CHAQUE DOMAINE, UNE DISCRETISATION ELEMENTS FINIS EST UTILISEE, ET SUR CHAQUE INTERFACE LE RECOLLEMENT EST ASSURE PAR DES ELEMENTS FINIS Q#1, LES ELEMENTS JOINTS. LES SCHEMAS SONT PRECIS D'ORDRE 2 EN ESPACE ET D'ORDRE 1 OU 2 EN TEMPS. LES VARIABLES SONT DEFINIES SUR DES MAILLAGES NON DECALES. LA METHODE PROPOSEE PERMET D'ASSURER LA CONTINUITE DE LA PRESSION, SOLUTION D'UN PROBLEME ELLIPTIQUE, ET DU CHAMP DE VITESSE, SOLUTION D'UNE EQUATION PARABOLIQUE, CELLE DE LA QUANTITE DE MOUVEMENT. DE PLUS, UNE EXTENSION DE LA METHODE DE RACCORD AUX GEOMETRIES QUELCONQUES (SURFACE GAUCHE) EST PROPOSEE. DES RESULTATS ET DES COMPARAISONS AVEC LE CALCUL MONODOMAINE SONT PRESENTES. DANS LE CADRE BIDIMENSIONNEL, DES ECOULEMENTS STATIONNAIRES ET INSTATIONNAIRES SONT ANALYSES ET L'ETUDE EST ETENDUE AU CADRE TRIDIMENSIONNEL.

This book was released on 1984 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA DISCRETISATION EN TEMPS DES EQUATIONS DE NAVIER STOKES INSTATIONNAIRES BIDIMENSIONNELLES POUR UN FLUIDE INCOMPRESSIBLE, PAR UNE METHODE DE DIRECTIONS ALTERNEES FAIT APPARAITRE DEUX SOUS-PROBLEMES: PROBLEME LINEAIRE DE DIFFUSION QUI NECESSITE LA RESOLUTION DES EQUATIONS DE STOKES ET PROBLEME NON-LINEAIRE DE CONVECITON. CES DEUX SOUS-PROBLEMES SONT RAMENES VIA UNE METHODE DE CONTROLE OPTIMAL, A UNE CASCADE DE PROBLEMES LINEAIRES DE HELMHOLTZ. COMPARAISON DES RESULTATS AVEC CEUX OBTENUS PAR UNE METHODE D'ELEMENTS FINIS. LES METHODES SPECTRALES NECESSITANT LA RESOLUTION DE GROS SYSTEMES LINEAIRES MAL CONDITIONNES ON CHERCHE A DIMINUER LA TAILLE DES SYSTEMES A RESOUDRE EN DEVELOPPANT UNE TECHNIQUE DE COORDINATION DE SOUS DOMAINES SUR UN PROBLEME LINEAIRE SIMPLE: LE PROBLEME D'HELMHOLTZ BIDIMENSIONNEL

Download or read book Acoustics Aeroacoustics and Vibrations written by Fabien Anselmet and published by John Wiley & Sons. This book was released on 2016-01-07 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: This didactic book presents the main elements of acoustics, aeroacoustics and vibrations. Illustrated with numerous concrete examples linked to solid and fluid continua, Acoustics, Aeroacoustics and Vibrations proposes a selection of applications encountered in the three fields, whether in room acoustics, transport, energy production systems or environmental problems. Theoretical approaches enable us to analyze the different processes in play. Typical results, mostly from numerical simulations, are used to illustrate the main phenomena (fluid acoustics, radiation, diffraction, vibroacoustics, etc.).
